nRF52840 Dongle windows 7

[dhla]

Hi 

We have some production equipment still running windows 7. We would like to update the nrf51 dongle to a nrf52 dongle.

But drivers for nrf52 dongle is not installed correct although I have installed the newest version of nrf connect? Isn't it possible to use a nrf52 dongle in windows 7?

In windows 10 its not a problem to find the dongle.

Hi Danny,

How do you intend to use the dongle, Bluetooth LE controller? 

What did you run on the nRF51 dongles?

There is\was an issue on Windows 7 and the 52 dongle. The Serial drivers need to be installed manually, assuming you plan to use the connectivity FW. 

Try these: https://github.com/NordicSemiconductor/pc-nrfconnect-launcher/tree/v3.7.0/build/drivers/dfu_trigger_and_cdc_acm

Hi,

What application is running on the dongle? Does it show in the programmer app?

Hi

The firmware on the dongle is what nrf connect (Blue Low Energy) loaded to the dongle first time it was connected to my own win10 PC.

I also tried to connect a new dongle with no firmware (so it started up in boot mode) to the windows 7 PC. It could also not detect that in nrf connect.

It can also not detect it with the programmer app
